Gun sight



FIG. 1 is a perspective view of a gun sight showing my new design;

FIG. 2 is another perspective view thereof; and,

FIG. 3 is an enlarged end view of FIGS. 1 and 2.

The broken lines are to show environment only and do not form part of the claimed design. 

I claim the ornamental design for a gun sight, as shown and described.
